Specification of Letters Patent.

Patented Feb. 22, 1916.

Application filed July 13, 1915. Serial No. 39,694.

To all whom it may concern Be it known that I, Fninnion Rinwn, a citizen of the United States, residing at Pottsville, in the county of Hamilton and State of Texas, have invented a new and usefuLBoll-VVeevil Exterminator, of which the following is a specification.

The device forming the subject matter of this application is adapted to be employed for collecting and exterminating boll weevils which, as commonly known infest cotton plants. I

One object of the present invention is to will be brushed into collecting troughs.

Another object of the invention is to provide a novel means whereby the collecting troughs may be cleaned out readily.

Another object of the invention is to provide novel means for adjusting the collecting troughs vertically.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the present invention appertains.

l Vith the above and other objects in view which will appear as the description procoeds, the invention resides in the combination and arrangementof parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed, without departing fromthe spirit of the invention.

In the accompanying drawings z-Figure 1 is a side elevation; Fig. 2 is a top plan; Fig. 3-is a perspective showing one of the troughs; Fig. 4 is a fragmental longitudinal section; Fig. 5 is an end elevation; Fig. 6 is cross section. V

In carrying out the present invention there is provided a wheel mounted frame comprising a pair of longitudinal sills 1 united adjacent their forward ends by means of a cross bar 2. U-bolts 3 or other elements adapted to the end in view unite an axle 4: with the longitudinal sills 1, the axle i carrying ground wheels 5.

The numeral 6 indicates a tongue connected by means of U-bolts 7 with the axle 4, the tongue 6 being secured as shown at 8 to the cross bar 2. The tongue 6 carries a double tree 9. Braces??? extend between the tongue 6 and the depending ends of the axle t. Mounted on the tongue 6 is a support 10 unholding a seat- 11.

The invention comprises a pair of collecting troughs 12 each including a bottom 14 and an overhanging side wall 15. As shown at 16, the forward edges of the bottoms 1d of the troughs 12 converge and as shown at 17, the forward, upper edges of the side walls 15 converge, so as to direct the standing plants between the troughs. To the longitudinal, adjacent edges of the bottoms 14: of the troughs 12, reinforcing strips 22 are secured. Journaled on the reinforcing strips '22'are rollers 18, in the form of flat wheels or disks, the construction being such that when the machine is drawn along, the wheels or rollers 18 will engage the standing plants and swing or knock the same transversely of the line of advance of the vehicle, to the end that insects on the plants may drop into the troughs. Flexible elements 19 which may be made of felt or the like, are secured to the longitudinal edges of the troughs 12 and project toward each other beyond the inner edges of the troughs, the function of the flexible elements 19 being to protect the standing plants and to prevent injury thereto as the plants pass between the troughs. Secured to the bottoms 14 of the troughs 12 near to the inner edges of the troughs are arcuate plates 20, the outer edges of which are free. The forward ends of the arcuate plates 20 extend into compartments defined at the forward ends of the troughs 12 by closure members 23 which are bridged across bottom portions 141 of the troughs 12 adjacent the forward ends of the troughs.

The troughs 12 comprise end walls 24: to which doors25 as shown at 27 are hinged for swinging movement in a substantially horizontal direction. The upright, inner edges of the doors 25 are rearwardly inclined to form converging lips 26 which serve to direct the standing plants out of the machine as the same isadvanced. Mounted on the rear faces of the doors 25 are keepers 28 in which are mounted to reciprocate, latch bars 29 provided at their upper ends with lateral handles 30 which prevent the latch bars from slipping downwardly out of the keepers 28. The lower ends of the latch bars 29 are adapted to cooperate with keepers 31 secured to the end of the troughs.

7 ends,

walls 24 of the troughs. It is to be observed that the doors 25 exercise a double function. First, they constitute a means whereby access may be had to the troughs, for the purpose of cleaning out the same. Secondly, since the doors 25 comprise rearwardly converging lips 26, the doors form a means whereby the standing plants are directed out of the machine, without injury to the plants, as the machine is advanced.

Disposed between the troughs 12 and located near to the rear and forward ends thereof are braces 32 having reduced ends 33 which extend beneath the side walls 15 of the troughs, the ends 33 carrying nuts 34 which engage the outer faces of the side walls 15 Springs 35 surround the reduced ends 33 of the braces 32, the springs 35 abutting at their inner ends against the braces and at their outer ends abutting against the inner faces of the sidewalls 15 of the troughs 12. As will be understood readily by tightening up the nuts 34, the troughs 12 may be adjusted horizontally with respect to each other, the springs 35 constituting a means for pressing the troughs laterally in opposite directions, so

that the troughs will cotiperate with the nuts 34.

Hook-shaped supports 36 extend beneath the troughs 12 adjacent the forward and rear ends of the troughs andare secured thereto, the supports 36 terminating in upright arms 38' loosely received in openings formed in the longitudinal sills l.

Bearings 39 are mounted on the longitudinal sills 1 near to the forward and rear ends of the troughs 12. In the bearings 39 are journaled transverse shafts 40 provided with rearwardly extended crank arms 41, the same terminating in loops 42 which surround the, arms 38 of the supports 36. Pins or like projections are mounted in the arms 38 of the supports 36 and are located above the loops 42, the construction being such that when the shafts 40 are rotated, the supports 36' and consequently the troughs 12 may be raised and lowered. Secured to the shafts 40 are upright levers 43; carrying, each, a latch mechanism 44 adapted to cooperate, with a segment 45 mounted on one of the sills: 1.

The inner edges of the sills 1 near to the seat 11 are provided with recesses 46 receiving standards 47 carrying at their lower inwardly extended, approaching brushes 48,.the brushes 48 projecting toward each other, and constituting a means for re moving the insects from. the standing plants, the construction under consideration being clearly disclosed in Fig. 6 of the drawings. Hook-bolts 49 or like elements pass through the longitudinal sills 1 and; engage with the standards 47 of the brushes 48 to hold the same in the seats 46. Obviously, by loosening the hook-bolts 49, the standards 47 may be rotated, thereby varying the angle defined by the brushes .48, and so adjusting the brushes that the same will cooperate with the standing plants.

The ope-ration of the device forming the subject matter of this application probably will be understood clearly from the foregoing, but it may be stated briefly, by way of recapitulation, that the forward and rear ends of the troughs 12 may be adjusted vertically by manipulating the levers 43. The troughs 12 may be cleaned out by opening the doors 25 in the rear end wall of the troughs and, as hereinbefore stated, the doors 25 constitute a means for directing the plants out of the machine, since the" doorsare equipped with rearwardly extended, converging lips 26. The brushes 48 exereise the functions hereinbefore'ascribed to them, and as hereinbefore pointed out, the

brushes may be adjusted properly with respect to each other by rotating the standard portions 47 of the brushes in the hook-bolts 49 or their equivalents.

In practical operation, the troughs may contain crude oil which maybe ignited to consume theboll weevils as they are col-' lected, and the function ofthe plates 20 is to prevent the contents of the troughs from splashing out.
